The more you open yourself to receive, the closer you get to Source/your true self/Godself, the more the timelines will come together and overlap to be experienced at once. The more I am able to hear my higher self or guides. Think of being completely unaware and earthbound as a straight line of yarn (linear time). Then when you bring the line closer to the center, it all bunches up and all the timelines start to overlap to be experienced at once. The more I bring myself inwards to reconnect with my true self/Source, the timelines start to merge and overlap. When reality slaps me in the face, and I lose my grasp, I lose all my abilities to see or hear, and I don't have those overlapping experiences anymore. Guess you have to experience it to understand.
